WILLIAM GRIPPEN, OF CADILLAC, MICHIGAN.

LOCOMOTIVE DRIVING=GEAR.

SPECIFICATION forming part of Letters Patent No. 266,103, dated October 17, 1882. Application filed August 12 1882. (No model.)

To all whom it may concern Be it knownthat I, WILLIAM ORIPPEN, of Cadillac, in the county of Wexford and State of Michigan, have invented certain new and useful Improvements in Locomotive Driving- Gear, of which the following is a full, clear, and exact description.

My invention consists of a crank-shaft ranging lengthwise of the locomotive, and located between the trucks and gearing with them by toothed wheels, the crank-shaft having universal joints, and also having provision for slidingin the driving-pinions on it in order to compensate for the deflections of the line and the variations of the length of the same, due to the curvatures and grades of the road. The crank-shaft and transmitting-gears are located in the longitudinal center of the locomotive to lessen the variations as much as possible. The object is to dispense with the expensive and complicated connecting-rod and side-bar gear and substitute a cheaper contrivance, and also to lessen the friction of the machinery, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan of a locomotive-truck of my invention inverted. Fig.2 is a transverse section, and Fig. 3 is a detail of the drivinggear in side elevation.

I use two four-wheel trucks consisting of wheels a, axles b, and frames 0, the frames being located wholly inside of the wheelsand fitted to the axles by boxes (I, on which truckframes the locomotive-frame e is pivoted at f by its bolsters g to allow the truck-frames the requisite lateral play for passing the curves. The pivot-bolts f have branches h resting on the side bars 0 of the truck-frames, and are fitted in the bolstersi of the trucks, which rest on the side bars j, to which the pedestals k for the axle-boxes are attached for the support of the locomotive-frame e by rollers l or other equivalent devices, allowing the trucks to shift under the locomotive-frame, as required by the curves. I

m represents the crank-shaft. It is located between the two trucks in bearing-supports attached to the locomotive-frame; or it may to the boiler to be Worked by engines locat on the boiler or on the frame 0, as may found the best. The shaft extends each w toward each truck, with which it gears by p ions 0 and bevel-wheels p on the axles fronti said'shal't, the shaft having universal joint to allow it to shift with the trucks, and bei fitted to slide in the pinions 0 as the length l tween the centers of the trucks changes w: the curves, the pinions being kept in place the bearings t and a, and the shaft being ted in them by feathers orsplines or by squat shapes, by which they may so slide while 2 plying the driving-power.

To drive on both trucks in the same dir tion the driving-shaftis arranged obliquely gear reversely with the bevel-wheels p, becat of being reversely connected with said whe in respect to their axles. The power is trai mitted to the other axles of these trucks means of the intermediate wheels, w, a wheels 00, thus utilizing the traction of all the wheels.

It will readily be seen that my arrangeme is much simpler and cheaper, and is adapt to work with less friction than the common: ran gement.

Having thus described my invention, wha claim as new, and desire to secure by Lettt Patent, is-

1. The locomotive-gearing 0019 w, arrang on the axles in avertical plane passing throu the longitudinal middle of trucks, in combit tion with a diagonal crank-shaft, m, havi universal joints and end pinions, and adapt to slide in said pinions, as and for the purpc specified.

2. The combination, in the running-gear o1 locomotive, of inside truck-frames, c, branch center pins, f, truck-bolsters i, pedestal-fram j 76, roller-supports l, and the locomotive-frat e, substantially as described.

WILLIAM ORIPPEN.
